Become more and more acquainted with your body on all its subtle levels, the fine vibrations which really are music, because when we talk of things created, they are only vibrations, nothing else, energy in movement and matter. In poetic language we can say the world is created by music. As we are the world, the universe, all the music of the universe is in our body.
The fitness of our hearts and thoughts to receive God's spirit is like that of violin strings. If they are properly tuned, in harmony with one another, then the touch of the bow produces beautiful music. If not, then there is only discord. Whenever our hearts are truly ready to receive God's spirit, they will produce heavenly airs and joyous harmonies -- both in this life and in the spiritual world.
